indicator

I am trying to efficiently create a binary dummy variables (1/0) in my data set based on whether or not one or more of 7 variables (col9-15) in the data set take on a specific value (35), but I don't want to test all columns. While as.numeric is ideal usually, I can only get it to work with one column at a time: data$indicator <- as.numeric(data$col1 == 35) Any idea how I can modify the above code so that if any of data$col9 - data$col15 are "35" then my indicator variable takes on a 1? Thanks!!! You can use rowSums (vectorized solution) like this : set.seed(123) dat <- matrix(sample(c(35,1

Is there a wat to make a indicator like this? it has some pointed arrow down like in the selected item? The only solution I could find is to grab the source code of the original TabLayout and customize it, according your needs. In fact, all you need to do to get this custom pointing arrow is to override SlidingTabStrip 's void draw(Canvas canvas) method. Unfortunately, SlidingTabStrip is private inner class inside TabLayout . Luckily, all support library code is open, so we can create our own TabLayoutWithArrow class. I replaced the standard void draw(Canvas canvas) by this one to draw the

I need to change the color of the disclosureIndicatorView accessory in a UITableViewCell . I think there are two ways to get this done, but I'm not able to figure out which one's the optimum. So here is what I think I can do. There is a property of UITableViewCell - accessoryView . So I can use setAccessoryView:(UIView *)view and pass view as the UIImageView holding the image that I want. I have written an utility class which creates the content view (stuff like background color, adding other stuff, etc) for my cell and I add this content view to the cell in UITableViewDelegate . The other

As regards to expandable list view, the group icon indicator is positioned to the left side, can I move the indicator and positioned it to the right? Thanks. EDITED: Since I don't want to extend the view, I got this workaround of getting the width dynamically. Just sharing my solution. Display newDisplay = getWindowManager().getDefaultDisplay(); int width = newDisplay.getWidth(); newListView.setIndicatorBounds(width-50, width); According to ExpandableListView 's source code, the only way to move an indicator to the right side is to change its bounds using ExpandableListView.setIndicatorBounds(

Probably many of you (as me), have problem with creating ViewPager with bottom dots, like this: How do you create such an Android ViewPager? RediOne1 All we need are: ViewPager , TabLayout and 2 drawables for selected and default dots. Firstly, we have to add TabLayout to our screen layout, and connect it with ViewPager . We can do this in two ways: Nested TabLayout in ViewPager <android.support.v4.view.ViewPager android:id="@+id/photos_viewpager" android:layout_width="match_parent" android:layout_height="match_parent"> <android.support.design.widget.TabLayout android:layout_width="match

I have a data.frame consisting of numeric and factor variables as seen below. testFrame <- data.frame(First=sample(1:10, 20, replace=T), Second=sample(1:20, 20, replace=T), Third=sample(1:10, 20, replace=T), Fourth=rep(c("Alice","Bob","Charlie","David"), 5), Fifth=rep(c("Edward","Frank","Georgia","Hank","Isaac"),4)) I want to build out a matrix that assigns dummy variables to the factor and leaves the numeric variables alone. model.matrix(~ First + Second + Third + Fourth + Fifth, data=testFrame) As expected when running lm this leaves out one level of each factor as the reference level.
